File Names
The conventions for the treatment of file names by the YMODEM protocol are:
• The source router or the remote workstation sends files with path names
stripped and limited to eight characters plus a three-character extension. The
router or workstation converts all file name characters to lowercase, and all
“:” characters to “/” characters.
• The target router or workstation stores received files under their transmitted
names. However, YMODEM converts / characters in the received file name
back to “:” characters. YMODEM also translates all uppercase characters into
lowercase, and eliminates any trailing dots in the file name.
• If you want to specify multiple file names in a single
xmodem
command (that
is, a YMODEM batch file transfer operation), insert a space after every file
name except for the last name you specify in the command line. You can also
use wildcards in a file name (for example, *.bat).
